APA3010/1 3W Mono Low-Voltage Audio Power Amplifier Features General Description Operating Voltage : 2.5V-5.5V Bridge-Tied Load (BTL) Mode Operation Supply Current – IDD=7mA at VDD=5V Low Shutdown Current – IDD=0.1µA Low Distortion – 2.5W, at V =5V, DD BTL, RL=3Ω, THD+N=0.1% – 2.1W, at V =5V, DD BTL, RL=4Ω, THD+N=0.1% Output Power The APA3010/1 is a bridged-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers. Operating with a 5V supply, the APA3010/1 can deliver 3.3W of continuous power into a BTL 3Ω load at 10% THD+N throughout voice band frequencies. Although this device is characterized out to 20kHz, its operation is optimized for narrow band applications such as wireless communications. The BTL con- at 1% THD+N figuration eliminates the need for external coupling ca- – 2.6W, at VDD=5V, BTL, RL=3Ω – 2.3W, at VDD=5V, BTL, RL=4Ω at 10% THD+N pacitors on the output in most applications, which is particularly important for small battery-powered equipment. This device features a shutdown mode for power sensi- –3.3W at V =5V, DD BTL, RL=3Ω tive applications with special depop circuitry to eliminate –2.7W at VDD=5V, BTL, RL=4Ω Depop Circuitry Integrated speaker noise when exiting shutdown mode. The APA3010/1 are available in a SOP-8, SOP-8P or Thermal Shutdown Protection and Over-Current MSOP-8P. Protection Circuitry High Supply Voltage Ripple Rejection Surface-Mount ...
